LUBRlCA-TING DEVICE.

SPECIFICATION forming part of Letters Patent No. 602,854, dated April 26, 1898.

Application filed March 12 1897. Serial No. 627,199. (No model.)

To all whom it may concern.-

Be it known that I, CHRISTIAN H. C. K0011, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvement-sin Lubricating Devices, of which the following is a description.

My invention relates to lubricating-pads, and has for its object to provide a new and improved lubricating-pad, reference being had to the accompanying drawings, wherein-- Figure l is a face view of a pad embodying my invention. Fig. 2 is an end view of the same. Fig. 3 shows the pad in position in a journal-box. Fig. 4 is a side view of the pad before it has been given its cylindrical shape. Fig. 5 is an end View of the same.

Like letters refer to like parts throughout the several figures.

The pad is made up of pieces of flexible materialsuch, for example, as felt. A series of pieces or sections A of the pad are bound together, as shown in Figs. 4: and 5, by means of a binding-piece B. The pad is then twisted until it takes the form shown in Fig. 1, wherein the edges of the pieces of felt are exposed, the entire surface of the pad being composed of these edges, so that the end of the grain is presented to the bearing. The pieces are held in this twisted position by any suitable means, as by means of the thread or wire or string D passed through the pad. These holding devices 1) maybe of any suitable description and may be located at any desired'part of the pad. Any number of such holding devices desired may be used. The end of the binding part B is preferably provided with a loop E, by which it may be withdrawn from the j carnal-box.

. In Fig. 3 I have shown the pads placed in the journal-box F. I prefer to place the two pads A and A in the journal-box, one being placed on each side of the journal G.

I have described the several parts of the pad in detail, but it is evident that the construction may be varied in many particulars without departing from the spirit of my invention, and I therefore do not wish to be limited to the construction shown.

The use and. operation of my invention are as follows:

When the pad is twisted so as to form a substantially cylindrical pad, as shown in Fig. 1, and it is desired to insert it in the journal, the operator grasps the ends of the pad and twists the folds of the felt, so as to reduce the size of the pad below its normal size. The pad can then be placed in the journalbox without any special eifort and without the need of any special appliances and also without in any manner changing the journalbox. When it is thus placed in the box and released, it tends to untwist, so as to return to its normal size, and this tendency insures its contaotwith the journal at all times. Any number of these pads may be used in any given journal, but I prefer to use two, the two pads being placed one on each side of the journal and being twisted in opposite directions, so that the rotation of the journal tends to twist the fold of one pad tighter and tends to nntwist the folds of the other pad and make them looser. By this construction one pad-that is, the pad which is untwistedacts as a wiper to wipe off the journal, as well as to lubricate the same.

It will be seen that I have here a pad which can be easily and quickly inserted in any journal-box and which by being reduced in size and then inserted will always be keptin contact with the journal by its tendency to return to its normal size.

I have shown a pad made of two pieces of flexible material; but of course one piece or any other number of pieces may be used, if desired.

I claim- 1. A lubricating device for journals comprising two pads made of felt or the like, twisted around a supporting device, so as to form substantially cylindrical pads which present the edge or grain of the felt to the journal, the two pads twisted in opposite directions and placed in the journal-box so that the motion of the journal tends to tighten the folds of one pad and loosen the folds of the other.

2. A lubricating-pad for journals comprising two sheets of felt or the like bound together near their middle, and twisted so that .the edges presenting the ends of the grain are exposed all along the surface of the pad,

the pad being substantially cylindrical, and a binding device connected with said felt so as to hold the sheets in position.

3. A lubricating-pad for journals and the like, comprising one or more sheets of flexible material bound together near their middle and twisted so that the edges presenting the ends of the grain are exposed substantially along the entire surface of the pad, a binding device for holding said flexible pieces in their twisted position, the pieces adapted to be more tightlytwisted so as to reduce the size and to allow the pad to be inserted in the journal-box, the tendency of said pad to untwist insuring contact of the pad with the journal.

4. A lubricating-pad for journals or the like, comprising two or more sheets of flexible material bound together near their middle and twisted so as to be formed into a cylindrical pad, the edges presenting the ends of the grain of the material being exposed and forming the surface of said pad, the parts so disposed that the size of the pad may be reduced before it is inserted in position by twisting the folds more tightly, said pad being kept in contact with the journal by the tendency of the folds to untwist.

5. A lubricating-pad for journals and the like, comprising a flexible pad made of flexible material, a holding device about which said flexible material is twisted, so that the edges of the material are presented to the journal, and a binding device for holding said flexible material in its twisted position.
